Piezoelectric power supply device in marine diesel engine and power supply method

Abstract

The invention aims to provide a piezoelectric power supply device in a marine diesel engine and a power supply method. A crank connecting rod linkage module comprises a linkage device, a piezoelectric power generation module comprises a vibrating body and a piezoelectric plate, the vibrating body is fixed on the linkage device, the piezoelectric plate is located in the vibrating body, an electric energy conversion module comprises a rectification circuit, an energy storage module comprises an electric energy storage element, current generated by the piezoelectric plate is transmitted to the rectification circuit, the rectification circuit is connected with the electric energy storage element, and the electric energy storage element is connected with electric equipment through an energy storage transmission circuit. The problem of complex wiring caused by the fact that an external cable penetrating through a diesel engine body needs to be connected when a wiring port of electric equipment in the diesel engine supplies power is solved, and the problem that replacement is troublesome due to the fact that a storage battery is arranged in the diesel engine is solved; signals detected by equipment such as a sensor can be transmitted out in a wireless transmission mode and the like, so that the convenience of power utilization of the equipment in the diesel engine is improved; and meanwhile, the mechanical energy of the crank connecting rod mechanism of the diesel engine can be fully utilized.

Description

technical field [0001] The invention relates to a power supply device and a power supply method, in particular to a marine diesel engine power supply device and a power supply method. Background technique [0002] As the "power heart" of the ship, the diesel engine requires a large number of electronic monitoring equipment and sensors in order to make its work run towards automation and intelligence. Due to the complex working conditions of diesel engines, various sensors are often required to detect state parameters such as position, temperature and vibration parameters and collect real-time data. In the traditional diesel engine, due to the introduction of sensors and magnetic switches, problems such as complicated wiring have been brought. [0003] Considering that the reciprocating linear speed change movement of the internal crankshaft connecting rod of the diesel engine can drive the movement of the internal generator of the power supply device, the movement of the ge...

AI Technical Summary

Problems solved by technology

Although this structure uses a crankshaft connecting rod combined with a piezoelectric device to generate power, the device uses the crank connecting rod in its own structure to drive the wheel mechanism to rotate to generate electricity, and the linkage of the power supply device and the power generation module are not fixed on the crank connecting rod. The whole set of devices is not suitable for the actual situation of the crank linkage mechanism inside the diesel engine
